OK, I'll give my impressions of a couple of them.
Image #1. This is apparently a monument to, in no particular order, #2 pencils, breast cancer awareness and Hedgehogs...
Great color and saturation, you really got the exposure quite nicely.
I think the image needed rotating a bit to the right, so here's my version.

Unfortunately, the construction detracts from the image, unless that's what you're documenting. If the shot is to show "Here's the construction of a new station", then it works. Otherwise, it's somewhat distracting in my opinion. The orange cones and the like catch your eye.
What can you do about that? Well, uh, nothing that I can think of other than go back when they're done. Lousy answer, eh?
The other option would be to try and different angle and/or go in tight on the sculpture, but then you lose the context.
